ASPEN, Co (Reuters) - Twitter co-founders Biz Stone and Evan Williams plan to revive Obvious, the company they conceived years ago as a technology project incubator that eventually spawned Twitter.

Stone and Williams will continue to advise Twitter on strategic matters, but devote the lions’ share of their time to The Obvious Corporation, Stone said on Tuesday.

"The Twitter crew and its leadership team have grown incredibly productive. I've decided that the most effective use of my time is to get out of the way until I'm called upon to be of some specific use," Stone said in a blog post. here

“Our plan is to develop new projects and work on solving big problems aligned along a simple mission statement: The Obvious Corporation develops systems that help people work together to improve the world.”

“This is a dream come true!” Stone said.

Dick Costolo replaced Williams as Twiter’s CEO in October, a move Silicon Valley sources have said re-focused the microblogging sensation on monetization, or translating its fast-growing pool of users into revenue.
